    Yes, I believe it will.... they havent changed the shape of the keyhole in years.

    1980 120hp

    the 2.5 morphed into the 3.0 which was used for MANY years after the 2.5 went the way of the dinosaur. Internal engine hard parts, such as what you are looking for are likely the same or interchangeable with the 3.0 of at least some vintages, and also automotive equivalents. This does not apply...

    benefits of side bunks..... are there really any?

    Agreed on power loading, hence why I USUALLY dont do it (our lake is up high enough at the moment that erosion is not an issue, there is still another 200 feet of concrete under us at the moment). I pull the boat on manually with lines after walking it on/off the trailer. one of the local ramps...

    benefits of side bunks..... are there really any?

    one of my boats has (had...) side bunks, the other does not. I really dont see much advantage to them, aside from a little better guidance to centering the boat when power loading.... It may be just me, but I dont have a problem centering either boat on its respective trailer... are there...

    1995 OMC Cobra v-6 will not rev out under load

    aaarrrrgghhhhhh... seems to be a case of "maintained by moron"..... swapped 4/6 plug wires back to where they are supposed to be, and lo and behold the engine idles and runs much better on the hose at least. (yes, I had checked it before, but it still eluded me.....) Before it was a little...

    Why is my gas orange?

    had more than one motorcycle tank that looked good inside, (even cleaned a few with muriatic acid) and they still turned the gas orange. keep an eye on the filter, and change as needed..... bout all you can do.

    Why is my gas orange?

    my first thought is rust...... even just a fine surface layer is enough to come off and turn things rusty orange looking..... plenty of areas you cant see in a tank that can/will harbor the stuff....

    1995 OMC Cobra v-6 will not rev out under load

    Ill double check the fuel system. Flappers I would not think are an issue. I have plenty of evidence of exhaust coming out the back of the boat both on shore and in the water. Engine runs "great" at idle and up to about 1500 rpm, then it falls flat on its face. Fuel pump is an electrical, and...

    1995 OMC Cobra v-6 will not rev out under load

    yes. firing order is correct ok, Ill admit... I went and checked AGAIN.... I had 4 and 6 reversed.... that will cause an issue.... Ill report back once I fire it up again... It should run MUCH better now both on muffs and in the water.... I have to wait for another water test, I kind of...

    1995 OMC Cobra v-6 will not rev out under load

    ok, finally got the '95 Four Winns (4.3 chevy with an SX in drag hanging on the transom) off the dock yesterday, only to find out it WILL NOT rev past about 1500 rpm in gear. In neutral it revs out fine..... so something is amiss in the engine department. (Prop is the standard 14.5x21 pitch it...

    Bravo trim rams on a pre-Alpha (MC-1)

    its gonna come down to part numbers, which the seller conveniently didnt list..... as I said, the seller didnt bother to ship properly, and has a few other sets of the same rams listed currently..... since Mercruiser changes part numbers like I change my underwear, there is probably some obscure...

    Bravo trim rams on a pre-Alpha (MC-1)

    ok, I got had on Ebay.... bought a set of trim rams that were advertised as for a Alpha One XD, but the part number comes back as Bravo rams (98703A26, 98704A26).... the bushings are ginormous on this, and as such my through bolts are too short.... Seller does not accept returns, and shipped...

    HOA rules say, no boats visible from the street,....

    trust me, I tend to agree with you.... its just for millions of folks that dont have a choice but to live in a metropolitan area, HOA's are the standard, and not the exception.....I would rather staple my johnson to the floor and fiberglass it down than live under an HOA..... but there is an...

    HOA rules say, no boats visible from the street,....

    while not forced, there is often little choice in the matter. Out here, you want a new(ish) home, you get saddled with an HOA... the developers and municipal governments LOVE them for some reason. I bought an older home (1950 built) and away from the main metropolis just for no HOA.... even...

    Mercruiser 3.0 diagnosis / serial number decode

    cheap parts will bite you.... I just replaced a less than three year old set of bellows because I went "cheap" chinesium parts..... I replaced with Sierra this time..... much thicker rubber, so hopefully will last better.... and were really no more expensive than the Chinesium crap from the...

    trim pump issues.....

    according to Mercruiser service bulletins, these pumps are non-serviceable as per Prestolite. Aside from o-rings, there are no parts available, and the specs for the pop-off spring settings are not published in the service manual... that said, yeah, I took mine apart to see if it was just a...

    trim pump issues.....

    yeah, I spent the last few days in the manual trying to make it not be the pump...... but its the pump... I pulled it off this morning and opened it up... full of crap, and the shuttle valve that controls the release of "up" side pressure in "down" mode is jammed solid.... no amount of...

    yes, it will drop like a rock when you disconnect a cylinder.

    trim pump issues.....

    I dont have access to a gauge, but I am getting good flow out of a disconnected line. There are no pipe plugs in the valve body. Someone before me had dicked with the check valves in the control body, so that could still be dorked up, That said, there is no restriction in the control valve on...

    trim pump issues.....

    motor runs in both directions. from what I can tell, the check valve on the "up" side is not releasing pressure for the fluid to return to the reservoir. No amount of banging on it has freed it up, its stuck GOOD..... pressure and flow are good, once you provide a "return" (cracked loose hose)...
